Corals vs Climate

Tracking Coral Bleaching Impacts, Tolerance, and Recovery to Build Resilient Reefs

Monitoring Coral Bleaching Impacts and Reef Resilience

We are leading coral bleaching research in Peninsular Malaysia. Our research tracks the effects of thermal stress on coral reefs to understand patterns of bleaching, recovery, and mortality across species and sites. By combining field surveys with statistical modelling, we identify key environmental drivers of bleaching and assess reef resilience to climate change.

Tracking Bleaching, Tolerance, and Recovery to Build Resilient Reefs

To ensure maximum restoration outcomes, we search for heat tolerant corals during mass bleaching events and select these corals for restoration.

A colourful struggle to survive

Not all bleaching turns corals white — some glow in vivid hues of blue, pink, and purple. This “colorful bleaching" is considered a struggle to survive, a last resort option. Yet, whether this strategy results in higher survival is unknown and a key research question for us.

The legacy of stress

This research explores how past heat stress influences coral resilience, revealing how previous bleaching events shape the future health and survival of reef ecosystems.

Impact & Insights

2019-2020

- marked the first back-to-back coral bleaching event in Malaysian waters, which we surveyed in detail.

2024

- saw the most intense and severest marine heatwave in recorded history in northeastern Peninsular Malaysia.

55.2%

- of coral bleached but only 1.1% died in 2019-2020. However, heat stress was not severe.

92.9%

- of corals bleached in 2024 and 78.3% of colonies suffered at least partial mortality at our sites. This underscores the existential threat of climate change for coral reefs.

34.1%

-corals died during the 2024 mass bleaching event in all of Malaysia.

only 14.7%

- of corals remained unbleached or fully recovered at our sites after the record-breaking heat stress event in 2024.
